Answer:

Explanation:

A)

The formula for regression is,

ln(Cell Phone Subscribers) = -820.894 + 0.411704 Year

or,

Percentage of Cell Phone Subscribers = exp(-820.894 + 0.411704 Year)

For the year 2005,

Percentage of Cell Phone Subscribers = exp(-820.894 + 0.411704 * 2005)

= 96.79%

B)

The significance of the slope has a p-value close to 0 (0.000). Hence, the model holds statistical significance and its predictions are very reliable.

Solution

1.Hotel’s cost structure          Indications in percentage(%)

Revenue                                     $ 2,000,000                          (100)

Less: Variable expenses            $ 1,300,000                            65

                                                    --------------------

Contribution margin                       $700,000                            

Less: Fixed expenses                   $560,000                            28

                                                    ---------------------

Net income                                       $140,000                            7

2.Revenue declines by 30 percent

Revenue                                     $ 1,400,000                    

Less: Variable expenses               $910,000                                                                                    

                                                   ---------------------

Contribution margin                       $490,000                  

Less: Fixed expenses                   $392,000                          

                                                    ---------------------

Net income                                       $98,000          

3.Operating leverage factor when revenue is $2,000,000    

       Operating leverage =    Contribution/ Net income

4.Operating leverage factor when increase in revenue by 25 percent  

increase in revenue by 25 percent=

increase in contribution by 25 percent=

increase in net income by 25 percent  =                                                  

       Operating leverage =    Contribution/ Net income

Response:

The answer to the question is provided below.

Analysis:

(a) What quantities of peanut butter and jelly will David purchase with his $3 weekly allowance?

It is stated that David prefers 2 ounces of peanut butter for each ounce of jelly, thus

2Pb = J, and the budget constraint can be expressed as 0.05Pb + 0.1J = 3.

Using substitution,

David will acquire Pb = 30 ounces, J = 15 ounces.

30(0.05) + 15(0.10) = 3

(b) If the cost of jelly rises to $0.15 per ounce, what quantities of each item would he purchase?

If pj = $0.15,

24(0.05) + 12(0.15) = 3

Using substitution, we find J = 12 ounces, Pb = 24 ounces.
